Specification of Letters Patent.

Application filed March 22, 1912. Serial No. 685,623.

To all whom it may concern Be it known that I, GEORGES FAUQUET, residin at Petit Quevilly-les-Rouen, Seine- Infrieure, France, have invented new and useful Improvements in Cleaning-Brushes for Collecting the Dust Produced During the Cleaning of Cards in Spinning-Mills, which improvements are fully set forth in the following specification.

In spinning mills, the cleaning of cards which has to be done several times a day on each machine, produces, a considerable quantity of very fine dust which fills the air in the shop and inconveniences more particularly the men intrus'ted with this operation. A number of arran ements have been already suggested for obvlating that drawback, but several of them are inefiicient or incomplete; others which give good results, comprise a fixed fan and cumbersome conduits with a branch opposite each card; considerable motive power is required, and the cost of the installation very high. The adjustment, at the conduit branches, of a movable hopper, its transport from one card to the other and the manipulation of the registers, are additional manipulations which multiplied by the number of operations, increase in the end the work of the men intrusted with this task.

This invention relates to a cleaning brush which at the same time collects the dust produced by the cleaning. This apparatus does not comprise any fixed installation. Its manipulation is as simple as that of ordinary cleaning, and finally the only expense incurred is the purchase price of the apparatus, which moreover is not considerable.

In order to make my invention as clear as possible, the same is illustrated in the accompanying drawings, in which by way of example a cleaning brush collecting the dust is shown.

Figure 1 is a view in vertical longitudinal section on line AA of Figs. 2 and 4. Fig.

2 is a vertical cross-section on line BB of Figs. 1 and 3, Fig. 3 is a horizontal crosssection on line CC of Fig. 2, Fig. 4 is a vertical cross-section on line DD of Fig. 1. Fig. 5 is a front elevation at the side of the fan, showing a device for driving the fan and the brush, which enables the speed of the fan to be increased without that of the brush being modified, when all the cards of the spinning mill are provided with drivmg pulleys at the same side. Fig. 6 is a vertical section, Fig. 7 a partial section on line EE of Fig. 5. Fig. 8 is an elevation from the side of the fan showing the drivmg gear for the fan and the brush, enabling the speed of the fan to be increased without that of the brush being modified, in the case when the driving of the cards of a spinning mill 1s alternately right and left hand. Fig. 9 1s a vertical longitudinal section of the whole of the device for the modified construction of Fig. 8. Figs. 10 and 11 are respectively a vertical cross-section and a horizontal cross-section of a modified construction in open position establishing communication between the suction chamber and the hood.

Fig. 1 shows the cleaning brush 1 (a cylinder provided with bent teeth 1) with its various parts, namely the hood 2 surrounding the brush 1 and provided at the top with a suction chamber 3 communicating with the brush by means of an opening 4 extending throughout the whole of its length. The said opening is narrower (Fig. 3) at the side Where the suction takes lace in order to equalize the latter by faci itating it at the side opposite to the fan 5. A centrifugal fan 5 is keyed to the spindle 6 of the brush 1 and communicates with the suction or exhaust chamber 3 of the hood 2 by means of a rigid pipe 7 connected, by means of a socket jomt 8 enabling it to have a certain movability, to the suction chamber 9 of the fan 5. The spindle 6 carrying the brush 1 and the fan 5, is provided at its end with a grooved pulley 10. This pulley in well known manner is operated by means of a cord placed around a grooved portion of the loose pulley mounted on the spindle. of the large card cylinder. The card cylinder is driven in well known manner from a suitable source by means of a belt transmission. When it is desired to operate the cleaning brush the cord is applied around the loose pulley and the belt is shifted so as to partly engage the latter, whereby movement is transmitted to the brush through the medium of the endless cord. This being a well known arrangement, the same is not further described nor shown.

The air charged with dust, is expelled by the action of the fan through the flexible hose 11 into the receptacle12 at the bottom of which a'little water can be placed. The widened shape of the mouth 13 reduces the speed of the air and thus facilltates the settling of the heavier dust. The air follows in the receptacle 12 a sinuous path, which completes the settling of the dust, and finally is discharged back into the workshop not far from the ground through the lateral openings 14 which can be covered with a band of fabric or filter cloth completing the purification. The single drive for the brush 1 and the fan 5 mounted on the same spindle, insures their synchronous movement and does not allow any dust to be disengaged without it being immediately collected. The manipulation of this apparatus does not require any supplementary operation by the cleaning attendants, or any increase in the time required for cleaning. Under certain circumstances, due to the arrangement of the cards and to the speed of their parts, and to the degree of cleanliness of the raw material treated, it may be advantageous to use two fans one mounted at each end of the spindle of the brush, and to modify their dimensions. This modification of course requires a suitable modification of the inner openings of the hood of the brush, so as to insure an always uniform suction at every point of its length.

The foregoing dealt chiefly with the case where the centrifugal fan keyed to the end of the spindle of the cleaning brush, is driven together with the said brush, by means of a cord operated by the loose pulley of the card. The fan rotates therefore with the same speed as the brush. In certain cases it may be an advantage to increase the speed of the fan without modifying that of the brush. This result can be obtained in the following manner: The spindle 15 (Figs. 5-7) of the cleaning brush provided with the grooved pulley 10 rotated by means of a cord from the loose pulley of the card, passes at one of its ends close to the pulley 10 through a hollow sleeve 16 to which are secured the fan 5 and a grooved pulley 17 of a suitably smaller diameter than that of the pulley 10.

A stud l8 firmly secured in the two cheeks of the fan, forms a pivot for a bell crank lever 19, one of the arms of which is controlled by a spring 20 while the other carries a stud forming a spindle for a small pulley or grooved roller 21 which is arranged slightly obliquely relatively to the pulleys 10 and 17, the axes of rotation of which are strictly parallel to those of the rotary parts of the card.

Fig. 5 shows by chain dotted lines the arrangement of the cord coming from the loose pulley of the card, partly surrounding first the small pulley 17 of the fan, then the pulley 21 which forms a guide and stretch ing device, then the pulley 10 of the brush, and finally returning to the'loose pulley of the card.

The preceding arrangement is applicable to spinning mills in which all the cards have the driving pulleys at the same side. When the cards are provided with the drive alternately at the right and at the left hand side, a slight modification becomes necessary.

It is advisable, as shown in Fig. 8, to secure to the cheeks of the fan a second stud forming a spindle for a grooved pulley 22 similar to the pulley 21 and arranged at the same angle, but in the opposite direction. This pulley is used as a guide for the cord which drives the large pulley 10 of the brush, the small pulley 17 of the fan and passes also over the stretching pulley 21. The path of the said cord is shown by chaindotted lines in Fig. 8. As the cord drives the fan and the brush, one by the other, at their respective speeds, but no longer passes over the loose pulley of the card, it is necessary, in order to drive the spindle of the brush, to secure to it at the end opposite to that carrying the fan, a grooved pulley 10' (Fig. 9) which is rotated by means of a. cord from the loose pulley of the cards which are driven from the other side than those referred to in the first instance. In that case, the attendants having to perform this work, first of all clean all the cards driven from the right by means of the cord shown by chain-dotted lines (Fig. 5). On arriving at the end of the workshop, they place the small cord as shown in chaindotted lines (Fig. 8) and then retrace their steps and clean all the cards driven from the left, by driving the brush by means of the pulley 10.

Figs. 10 and 11 of the accompanying drawing show that it is advantageous to shift the opening 4 toward that of the walls of the suction chamber which is the farthest away from the part to be cleaned or stripped. This arrangement enables in fact centrifugal force to be utilized for improving the suction. One of the edges of the opening 4 is in line with one of the generatrices of the cylinder which forms the hood 2, and the other edge is'oblique, so that the said opening is narrower at the side Where the suction takes place, in order to equalize the same by facilitating it at the side opposite to the fan.
